Commissioned in 1996 at Toroshima Royal Shipyards, the Vengeance Class of nuclear attack submarines are the silent killers of the South Mirthanese navy. It carries a mix of armaments with a crew of 58. The Vengeance class weighs almost 2000 long tons, has a top speed of 24 knots (27 mph), and a max dive depth of 900 feet. There have been 12 commissioned, without a single ship loss. The Vengeance measures at a length of 147 studs with a width of 12 studs.

With a speed of 24 knots, cavitation (pressure bubbles created by displaced water) is a real concern, which can be detrimental to the silence of a submarine. To help combat this, the submarine uses a skewback propeller design to lessen the effects of cavitation at shallower depths.

The Vengeance Class has 4 torpedo tubes capable of firing both cruise missiles and torpedoes. The tubes have also been used on occasion to deploy divers. The ship also carries magazine space for 20 addtional weapons.

With Nuclear propulsion, the Vengence class only needs to refuel once every 90 years. Many expressed concern over the if the ship were to sink. However the problem is minimal, the sea already contains trillions of tons of natural radioactive material, a few tons more will do nothing, and the ocean remains an infinite source of cooling and prevents meltdown.

in addition to soundproofing, to reduce noise, The Vengeance is also covered in anechioc tiles to reflect incoming sonar. (in case you're wondering, over 1600 1x1 tiles were used.)

The Conning tower is where the captain and a small number of staff commands the submarine. It contains communication lines to all decks and stations on the ship

For various purposes, the sub carries a periscope, although its seldomly used in combat.

The Conning tower houses a radar mast, which can be raised to detect enemy ships using radar.

I worked in a defense contractor once and they had a 100 x 50 x 30 foot high anechoic room.They used it for testing antennas, sending and receiving signals.Thousands of 30" long foam pyramids everywhere.

I also couldn't help but notice your other models on the table near the submarine and the destroyer. Did you buy all that or did you get from someone? Were do you buy your bricks?

Again, this is cool!

All South Mirthanese models (apart from the Harrier Jets) are all my own designs, built in LDD and then parts purchased over bricklink. Theres also a small family-run lego store near where I live, and I occasionally buy parts there. Any historical models, such as the T-72, M60, Panzer IV etc. are bought from brickmania, (with exception of my M113) though I sometimes add a few of my own modifications to them.

Thats very cool. and it seems I made a spelling error. most Submarines used anechoic patterns like you mentioned as soundproofing to limit noise, on the outside the tiles are rubber sheets filled with air bubbles.
